This species has been confused with Gonocarpus teucrioides but can be distinguished by its lax habit, flowers all alternate in a more sparse inflorescence, smaller brown bracteoles and 4 stamens (sometimes also with 4 staminodes). A variant with exceptionally large leaves to 3.5 cm long and to 1.8 cm wide has been noted in the Grampians.
